So I've done something silly and just piecemealed my drives as I've bought them. I have 4x 4TB disksx and 1x 2TB (for a total of 18TB of storage).
Because of this piecemeal nature, my files are spread out (e.g., "Movies1" on Drive A, "Movies2" on Drive C, etc.). It can make things a little confusing.
What I want to do is get an external RAID enclosure, fill it with 4x 4TB drives, put them together in RAID 5, and then go through the time-consuming task of copying and condensing my folders down into a new "TV/Series," "Movies," "Music" and "Comics" folders, while keeping my original drives in the NAS for backups, program settings, additional storage, etc.
Is this a feasible upgrade path? Would I suffer for plugging my RAID enclosure into USB3 ports on my NAS housing? Is there a smarter way to do this?
